Writing a book like this has always been a journey of exploration for myself, and I'm truly grateful that I also have the opportunity to share the results with you. The process has involved many discussions with the Windows engineering team who created the platform, often taking me into far-off corners of the galaxy, so to speak. I've also been doing my best to follow app-building discussions both within Microsoft, on the MSDN forums, and StackOverflow so that I can try to anticipate and answer questions that will likely arise in your own mind. And with this over-abundance of information and experience, my goal has been to pull together a narrative story from start to finish, blazing a single trail through what can seem at times like a thick jungle. I would love to hear from you how successful I've been at this endeavor.
